Claims.

This invention relates to a new and improved swinging spout forV faucets or the like and has for one of its principal objects the provision of novel means for effecting a stop in either direction of the swinging spout mounting. Specically, a locking member is preferably employed which performs two functions, namely (1) that of locking the spout against longitudinal movement in the mounting, and (2) that of limiting the arcuate movement of the swing spout to thereby prevent the accidental discharge of Water outside the sink.

An important object of this invention is to pro- Yvide a locking ring for swinging or rotatable spouts which is enclosed within the spout mountlng and preferably positioned below the packing, whereby leakage is effectually prevented. i Heretofore, in the prior conventional constructions employing a set screw to `limit the amount ofrotation of a swinging spout, leakage past thejoint has been a serious problem. I

, Another important object of this invention is to provide a C-form or semi-circular locking ring for swinging spouts which is simple and economi- `cal to manufacture, and relatively easy to assemble..

Other and further important objects will become apparent from the disclosures in the fol` lowing specification and accompanyingdrawing,

I Fig. 3 is an enlarged sectionalV view `taken onV the line 3-3 of Fig. 1 and shows the rotatable or swinging spout mounting of this invention.

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 3.

Figs. 5, 6 and 7 show modified forms of locking members within the terms of this invention.

Fig. 8 is a sectional view taken on the line 8-8 of Fig. 7.

As shown in the drawing: The reference numeral I indicates generally a dual faucet or the like having operating handles 2, an outlet 3, and a tubular swinging spout 4 rotatably mounted thereon, as indicated. As best shown in Fig. 3, the spout 4 has a mounting therefor consisting essentially of a housing 6 having a central recess and a shoulder I0 at the lowermost portion upon which the novel locking member 8 is supported. 'I'he housing 6 may be an integral part-of the faucet body as it is shown, or may be made as a separatepart. Means of attachment such as a bolted flange may be used or it may be screwed on or connected by a union ring, as presently indicated. The washer 9 is placed over the locking member 8 and resiliently held down by the packing II, with the gland I2 arid the gland nut 'I threadedly engaging the housing, as indicated.

The locking member 8, as best shown in Fig. 4, is semi-circular in shape and in a preferred form is made with diametrically opposed projections I3 and I4 which nt into oppositely aligned vertical grooves in the housing 6; As shown more clearly in Fig. 3, these grooves extend upwardly within the housing E a short distance from the shoulder I0. Immediately opposite the outwardly extending projection I4, as shown in Fig. 4, the projection I6 extends inwardly into the annular slot I1 cut in the lower peripheral portion of the wall of the spout proper 4. As shown in Fig. 4, it will be seen that the annular slot I1 in the spout 4 is slightly less than a semi-circular segment. As evidenced in Fig. 3, the thickness of the slot I'l is greater than the thickness of the locking ring 8 and its inward projection I6. The size of this segment Il designated as being substantially semi-circular may, of course, be any size segment of a circle depending on the particular application with which it is employed. I. .i

It will now be apparent that the locking ring performs the functions of preventing the spout from being withdrawn from its mounting, Aand of limiting the rotation of the spout by meansof the inwardly extending projection I6 of the locking member 8. With the packing I l, the gland I2 and the gland nut 1 positioned above the locking member 8 it is impossible for the latter member to be withdrawn thereby making it impossible for the spout to be withdrawn unless these latter described elements are first removed. `It is apparent that by the inward projection I6 acting against the ends or limiting edges of the slot I1 in the spout 4 the limits of rotational movement of the spout or rotatable member are established. When the spout is rotated in one direction it will be permitted to rotate until the edge of the slot Il strikes the projection I6 causing it to stop. Likewise, when the spout is rotated in the Vopposite direction, the opposite edge of the slot I1 `will strike the projection I6 and cause the spout to stop its rotation.

It is clear therefore that if the locking member B were permitted to rotate the spoutl would like- Wise be permitted to rotate without limitation and thus the inward projection I6 would be of no use. Therefore; the outwardly extending projections L3 and I 4 are nested within the slots in the housing 6 and prevent rotation of the locking member. It is obvious, however, that the projections I3 and lli on the member 8 could be made a part of the housing S `and the member B would then be slotted to receive such projections; in this way the same result of having a nonturning locking member would be accomplished.

The advantage of having a spout with a limited swing is quite obvious when it is seen that the faucets are generally mounted at the rear of a kitchen sink or the like, and if the spout should swing entirely around part of its swing might position the discharge spout at a location other than over the sink basin proper with resultant damage to iioors, wallsI and ceilings. It has been common practice, heretofore, to employ a set screw in place of the locking member in order to limit the rotational movement of the spout.

However, the tapping of the housing S for the presently used set screw has been objectionable inasmuch as leakage occurs at this point. The advantage lies in that the locking member 8 being superposed respectively by the washer 9, the stuning box packing II, and the combined stufng nut 'I and gland yI2 makes it virtually impossible for fluid to leak therepast suchfa's is the case when the conventional set screw is `used as just described.

It will be evident that the locking member shown as semi-circular may also be made as a part of a circular section and as used in its preferred form has an inward projection and, in addition, outer annular means such as the `projections I3 and i4 for preventing its rotational movement. However, it is readily foreseeable that the projections I3 and I4 may assume a variety of diierent forms such as grooves or the modifications of projections, etc. shown in Figs. 5, 6 and 7. Fig. 5 shows a novel type employing numerous angular projections I8 which are adapted to bite or rit snugly and nonrotatably into the recessed portion of the casing 6. Fig. 6 shows an inward projection I9 similar to the inward projection I6 of the member-8. However, in this locking member there is no outward projection but rather downward/extensions 2I adapted to be recessed in similarly shaped sockets in the shoulder III of the housing '6 'and in this manner inhibit rotation of the C-shaped locking ring. The ring vshown in Fig. '7 is similar to the semi-'circular ring 8 in that ,it has an inward projection 22 similar to the projection I6 on ring 8. However, in this construction the projections on the ring shown in Figs. Sand 6 are omitted, and instead, semispherical projections 23 and 24 are preferably punched (or they may be cast or otherwise formed) on the underside of the ring, as indicated. In this construction vthe shoulder Ii] of the housing 6 is of necessity provided with semi-spherical depressions or holes to engage the projections 23 and 24 in order that no rotational movement of the locking ring will take place.

Thus it is apparent that numerous details of the construction may be varied throughout a wide range without departing from Vthe principles disclosed by this invention, and I, therefore, do not propose limiting the invention otherwise than as necessitated by the prior art as viewed in light of the appended claims.
